6.113
It is the characteristic mark of logical propositions that one can perceive in the symbol alone that they are true; and this fact contains in itself the whole philosophy of logic. And so also it is one of the most important facts that the truth or falsehood of non-logical propositions can not be recognized from the propositions alone.

In 6.113 he maintains that logical propositions are characterized by their truth being self-evident, in the manner of immanent rationalism, rather than their truth being predicated on some extrinsic condition (empirically or rationally). What I am unclear on, is whether this whole project of the Tractatus, namely of setting out to frame a logical system in full propriety, is ultimately geared around devising a robust practical heuristic for better knowing how to ask potent questions, or how to avoid asking misguided questions; and whether, as part of devising such a heuristic framework, the framework itself needs to acknowledge its own limitations by disavowing itself.
